Introducing the Trinket Platter [Update]

Adafruit sells this great lit­tle micro­proces­sor called the Trinket. That last link is to the 5v one, but there is also a 3.3v vari­ant. They are a great lit­tle devel­op­ment board, based around the Atmel ATtiny, for when a full Arduino is just too much pro­cess­ing power and too much cost.

There is an upcom­ing project that I am work­ing on that is per­fect for a Trinket. It will be on my desk, con­nected to an AC adapter and a few remote com­po­nents such as LEDs and but­tons. I am not com­fort­able with hav­ing a bare Trinket just dan­gling and slid­ing around the desk. A full enclo­sure feels like overkill. I thought I would, instead, go with a mount­ing plate. The Trinket and power jack can mount directly to the plate; the wires and con­nec­tions can zip-tie to the plate as a strain-relief.

I took a few mea­sure­ments and set about to design­ing a 3D model to print.


I ended up with the fol­low­ing design, which I’m call­ing the Trinket Platter. The Trinket con­nects to the base with M2 screws. The DC power jack panel-mounts to the ver­ti­cal sur­face. You can zip-tie wires to oval hole. Because the 90-degree angle between the two sur­faces is a stress point, I designed that cor­ner with its own form of strain relief. The out­side edges have quarter-circles. The inside cor­ner edge is rounded, not sharp.



After print­ing and ini­tial test mount­ing, I ended up with this:



The 3D file, the OpenSCAD source file, and more detailed instruc­tions can be found on the trinket-platter GitHub page. You’ll see more of this lit­tle guy in the com­ing month.

Update: Apparently I only set up the GitHub project page with­out also upload­ing the STL to Thingiverse when I pub­lished this arti­cle. You can now find it on Thingiverse.
